To all whom it may concern/.-

Be it known that I, JOHN S. MERRILL, of

Columbus, in the county of Franklin and State of Ohio, have invented anew and Improved Bracket for Electric Lamps, of which the following is aspecification, reference being had to the annexed drawings, forming apart thereof, in which- Figure 1 is a side elevation of one form of myimproved bracket, and Fig. 2 is a modification of the same.

Similar letters of reference indicate corresponding parts in both views.

The object of my invention is to provide a swinging bracket for holdingelectric lamps in the position of use.

My invention consists in the construction and arrangement of parts, aswill be hereinafter fully described and claimed.

The flange A, which is designed for attachment to the wall B, isprovided with the central opening 0, which is screw-threaded to receivethe end of the rod D. The said flange A is apertured to receive screwsa, by which it is attached to the wall. erably provided with a squarehead I), and to the said rod'D is jointed a rod E, provided at oppositeends with square heads 17 11 The heads Z) l) are connected togetherpivotally by the rivet c.

To the rod E is joint-ed the rod F by the rivet c, which passes throughthe head 12 formed on the said rod F, and the head b of the rod E. Thefree extremity of the rod F is curved to form a hook d, for receivingthe eye 6, attached to the lamp G, and upon the rod F is placed anapertured plate f, which is pressed forward against the end of the hook(Z by a spiral spring g, which abuts against a collar 71, secured to thesaid rod F.

1n Fig. 1 the conductors H of the lamp G are connected in the usual waywith the main conductor independent of the jointed bracket.

The rod D is pref-' In the modification shown in Fig. 2 the rod F isangled, forming, in connection with the spring-pressed ring f a clampfor grasping the conductor H, the said conductor being held between theangled end of the rod F and the ringf.

Any desired number of rods may be jointed together in the mannerdescribed, so as to give a wide range of adjustments, and they maybemade to hold one or more lamps, as may be required. The flange A may beat tached to a base; or it may be made thick enough to form a base, sothat the lamp-support may be placed on the table in the same manner asan ordinary lamp.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- 1. The herein-described bracket, consisting in theplate A, having a screw-threaded aperture, the rod D, havingascrew-threaded inner end entering said aperture and provided with ahead 6, the rod E, having a head h pivoted to the head I), to swingtransversely to rod D, and having at its opposite end a head 12 the rodF, having a head b pivoted to head b at right angles to the pivot ofheads 1) b, and having its opposite end bent outward, aplate or armsliding on the outer end of rod F, and a spiral spring encircling therod and press ing the plate toward the said outward-bent end,substantially as set forth.

2. In a bracket, the rod F, having an outward-projecting arm at itsouter end, an apertured plate sliding on said rod, and aspiral springencircling the rod and pressing the plate against the inner face of saidoutwardprojecting arm, said plate and arm forming parallelclamping-surfaces, between which a wire may be held, substantially asset forth.
